Answer:
The types of DNA and the bones structure
Explanation:
bc many of these animals had descends of other animals and we can see it by the bone structure that they are almost the same
Answer:
Explanation: In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into or out of, the cell by moving down it.
Answer:
In case of these gram-negative bacteria, the outer membrane (made of lipid) is firmly bound to the cell wall (made of peptidoglycan). This structure is responsible for maintaining cell integrity against the turgor pressure faced from the outside. Since this outer layer is more permeable to substances moving across the membrane, the next layer - the inner membrane - also adds support to withstand turgor pressure. It will not let an osmolyte (such as sucrose) diffuse through it, thereby maintaining the osmotic pressure in the periplasmic space.
Hope that answers the question, have a great day!
